Laboratory tests on aggregates

Laboratory tests are standardised tests on aggregate samples that serve to determine a specific characteristic of the sample.

The following tests are available

- determination of particle size distribution; dry or wet sieving (UNI EN 933/1);

- determination of wear resistance - microDeval (UNI EN 1097/1);

- determination of the freeze-thaw resistance of aggregates (UNI EN 1367/1);

- determination of the fragmentation resistance of coarse aggregates - Los Angeles test (UNI EN 1097/2);

- determination of the polishability value (VL).

Technicians in charge of structural works.

The test may also be requested by companies or citizens (in which case no certificate but a test report will be issued).

Fill in the 'General Request' and 'Annex 1_Inert Tests' forms and hand them in at the acceptance desk of the Materials Testing Laboratory together with the samples to be tested.

The certificate is issued in digital format and is sent to the construction manager or the applicant by certified electronic mail (PEC).
